LHR - Euston Etihad Chauffeur - Allow how much time

[ishin]

Hi.....travelling Diamond First MEL-AUD-LHR and arrive at LHR 07:15 on a Saturday.

How much time should I allow to get through customs / immigration and travel via Etihad chauffeur to Euston to pick up a train connection?....also any advice on peoples experience of contingency I should add on this for flight delays on the AUD - LHR leg (I don't mind spending a bit of time at Euston)?..don't really want to miss my train as It would be pre-booked and difficult to take a later one (just additional cost).

Regards
ishin
